Abstract
With the development of the new energy industry, all walks of life have higher and higher requirements for the quality of the power grid, and the operation of the power system in different regions is different under the influence of many factors. In order to conduct a preliminary assessment of the operation of the power system by synthesizing various impact factors, the “Entropy-TOPSIS multi-objective evaluation model” was adopted to analyze and evaluate the relevant impact factors of six provinces in China (labeled U, V, W, X, Y, Z, respectively).The T-values of each province wereobtained, and preliminary conclusions were drawn as follows: The four provinces of U, W, Y and Z belong to the “good coordination”, the province of X belongs to the “good coordination”, and the province of V belongs to the “slight imbalance”. However, due to the errors of the index systemand model theory, the accuracy of the results needs to be further improved. In the future, double-cycle coupling can be extended to multi-cycle coupling, and related problems can be further studied.
